PEN is the Project Explorer for NEES. It is a java tool intended to run on a remote workstation or in the hub. The primary purpose of PEN is to organize files and directories for upload and download with the NEES Project Warehouse while a project is in active development.

PEN works on a single NEES project at a time. PEN helps you organize a local directory tree according to the NEES project data model.  It also provides an interface to edit object information including Title and Description.  An object is either a project, experiment, simulation, trial, run, repetition, directory or file.    PEN allows you to upload or download individual files or entire objects.

PEN is in active development by NEEScomm IT. NEEScomm IT is soliciting your feedback to improve PEN.  NEEScomm has dedicated resources that will continue to develop and support PEN.. Problems will be addressed using the NEEShub ticket system. Please enter tickets from the page you are on.  You may also enter wishes from the wish tab on this page.
